Motor vehicle forward structure

Abstract

A motor vehicle forward structure is provided with at least two vehicle chassis beams, at least two crash boxes, which are arranged at the front ends of the vehicle chassis beams, and at least one transverse beam structure, which is secured to the crash boxes. The transverse beam structure exhibits two transverse bumper carriers with a first transverse bumper carrier above the crash boxes, and a second transverse bumper carrier below the crash boxes. The crash boxes are fixed in a left and right end area of the transverse beam structure, between the transverse bumper carriers and at the ends of the vehicle chassis beams.

What is claimed is: 
     
       1. A forward structure of a motor vehicle, comprising:
 at least two vehicle chassis beams; 
 at least two crash boxes are arranged at front ends of the at least two vehicle chassis beams; 
 at least one transverse beam structure secured to the at least two crash boxes, the at least one transverse beam structure comprising:
 a first transverse bumper carrier arranged above the at least two crash boxes; 
 a second transverse bumper carrier arranged below the at least two crash boxes, and 
 
 wherein the at least two crash boxes are fixed in a left end area and a right end area of the at least one transverse beam structure between the first transverse bumper carrier and the second transverse bumper carrier and at ends of the at least two vehicle chassis beams, 
 wherein the first transverse bumper carrier exhibits a closed and an oval-shaped hollow profile, and 
 a longitudinal axis of the oval-shaped hollow profile of the first transverse bumper carrier is downwardly inclined toward an interior of the motor vehicle. 
 
     
     
       2. The forward structure according to  claim 1 , wherein a bumper composite plate is fixed in a central area between the first transverse bumper carrier and the second transverse bumper carrier and divides a gap between the first transverse bumper carrier and the second transverse bumper carrier into a left cooling channel and a right cooling air channel. 
     
     
       3. The forward structure according to  claim 1 , wherein the second transverse bumper carrier exhibits a closed and an oval-shaped hollow profile. 
     
     
       4. The forward structure according to  claim 3 , wherein a longitudinal axis of the oval-shaped hollow profile of the second transverse bumper carrier is upwardly inclined toward an interior of the motor vehicle. 
     
     
       5. The forward structure according to  claim 1 , wherein the closed and the oval-shaped hollow profile of the first transverse bumper carrier opposite A front side exhibits a conically increasing cross section. 
     
     
       6. The forward structure according to  claim 3 , wherein the closed and the oval-shaped hollow profile of the second transverse bumper carrier opposite A front side exhibits a conically increasing cross section. 
     
     
       7. The forward structure according to  claim 1 , wherein the first transverse bumper carrier and the second transverse bumper carrier are configured such that the at least one traverse beam structure has a frontally enlarged inlet cross section.
